Building Flexibility with Stay Set Hoses and Magnet Bases

You can build in flexibility when purchasing Super Air Nozzles, Air Knives, Safety Air Guns and other products from EXAIR. Consider adding our Stay Set Hoses and Magnet Bases to create flexibility and ease of set-up to your process. These accessories will improve your project and reduce your set-up time.

EXAIR has a variety of lengths in our Stay Set Hoses ranging from 6″ up to 36″ in 1/4 MNPT x 1/8 FNPT or 1/4 MNPT x 1/4 MNPT fittings. The Stay Set hoses are used mainly where frequent repositioning is required. You can bend and the hose to your desired position and since the hose has “memory” it will not creep or bend. It will keep this position until physically moved to the next position. These hoses can withstand temperatures up to 158 F (70C).

EXAIR Magnet Bases can be used when frequent movement of air product is required. These powerful magnets permit horizontal or vertical mounting. A valve is used to vary force and flow. The choice of single outlet, dual outlet and Swivel are available.

The combination of our Stay Set Hoses and Magnet Bases will accommodate Air Nozzles and Jets along with our smaller Air Knives, Air Wipes, Super Air Amplifiers and can also be assembled to our Safety Air Guns. There are many uses for our Stay Set Hoses and Magnet bases. While purchasing our Intelligent Compressed Air products consider all of our accessories to help your projects. If you have an application and have questions please contact EXAIR and one of our Application Engineers to answer your questions.

Turn the Pressure Down, Save Operation Costs

I recently recommended to a customer to turn their air pressure down on their system as low as their process would allow. Meaning regulate the pressure so you have enough to complete the operations needed but find that happy medium where your compressor isn’t working as hard to build those high pressures for no reason!

Compressed air is an amazing tool to have, and when used properly it can be more efficient that other non compressed air tools that run off electricity. How ever its pretty common to see compressed air systems running at their max just because.

Lowering the air system pressure reduces the compressor power consumption by about 1% for every two psi of lower pressure. Lowering the pressure also makes any unregulated operations reduce consumption by almost 1% for every one psi of pressure reduction. Not to mention the extra savings if your compressor system can turn down the compressor power because of the reduced flow and possibly shut off compressors that are no longer needed!

The best pressure at which to set your system is the level where your production can operate efficiently and effectively without waste: There is no right pressure—it depends on your operations and tools. You may have 90 to 100 psig at the compressor, but at the production machine, where the actual work is being done, you could have only 65 to 70 psig. In some cases, it may be even lower due to pressure drops in undersized piping, filters, regulators. The goal is to lower compressor discharge pressure without affecting the the operations at the end of the line.

Having artificially high plant-pressure can help you deal with surges in compressed air demand that might occasionally cause low-pressure and affect production. The higher pressure acts to store reserve air in the various volumes made up of receivers, pipes and such in your system. However, the higher pressure costs more to produce and makes unregulated end uses consume more air, which is an expensive trade-off. Another option is to make sure you have line pressure regulators at each point of use. This will allow you to regulate the operation to the pressure needed being sure to save compressed air and keep the over all system running more efficient.

You can regulate those point of use lines with a number of EXAIRs Pressure Regulators!

EXAIR offers a range of Pressure Regulators capable of handling air flow of up to 700 SCFM.

If we can help size a regulator, or have any other questions on how EXAIR can help you save compressed air in your system please reach out to me or one of our other Application Engineers!

Silencing Mufflers

I live near an amusement park called Kings Island. In the later part of Spring I can hear and see the people and rides. As the Summer enters and the tree leaves have all grown they act like a muffler reducing the roller coaster noises and screaming people on the roller coasters. These trees are not high enough to block the nightly fireworks but this is a good thing for me as I enjoy the sights and sounds of the fireworks.

An important focus in every manufacturing environment is a “Noise Reduction” campaign making a safer and healthier area for people working in the environment. EXAIR has Silencing Mufflers that can support your efforts for noise reduction. We have a variety of mufflers which will help to reduce work area noise produced by air exhausting from cylinders, valves and other air powered equipment. EXAIR Silencing Mufflers help plants meet OSHA Standard 1910.95(a) by reducing the sound to safer levels. Not only do our Silencing Mufflers reduce sound but they also eliminate harmful dead end pressures by covering up an open port or opening. These openings do not have a pathway for harmful pressurized air to escape if they become blocked.

Sintered Bronze Mufflers: A low cost solution and easy to install in new and existing air powered products. Sintered bronze muffler come in a variety of sizes (10-32 thread size up through 1/2-20 UNF female) and are capable of passing a certain volume of air with minimal back pressure restriction.

Reclassifying Mufflers: These mufflers are an upgrade from Sintered Bronze Mufflers. They offer the best noise reduction, up to 35 decibels. Available from 1/8 NPT up to 1 NPT. Reclassifying Muffles also eliminate oil mist. The patented wrap design of the removable element separates oil from the exhausted air so virtually no oil is released into the environment.

Straight-Through Mufflers: These mufflers offer a corrosion resistant aluminum outer shell lined with sound absorbing foam for better noise reduction. The typical noise reduction is up to 20dB.

Heavy Duty Mufflers: feature a corrosion-resistant aluminum outer shell with an internal stainless steel screen that protects valves and cylinders from contamination that could enter through the exhaust ports. The typical noise reduction is up to 14 dB.

EXAIR can help in your noise reduction projects with many options to consider. If you have any questions or need help selecting the right muffler for your needs please contact any of our qualified Application Engineers.

Undersized Regulators Create Performance Problems with Compressed Air

“I have a Cabinet Cooler installed on my panel but it isn’t getting the temperature down cold enough. Can you quote me for a duplicate system to install on this panel?” This was a recent inquiry from a customer regarding an electrical enclosure that they had installed in their plant. The Cabinet Cooler was producing cold air, but not enough to keep the cabinet at their desired temperature. It would seem logical that they need additional capacity, right? While that could be the case, in this instance it most definitely was not.

When we get questions like this, we first want to take a closer look at the current installation. The cooling capacity for each system is published in our catalog. BUT, in order to rate a cooling capacity for any type of cooling system, some assumptions must be made. All Cabinet Coolers are specified with 70°F compressed air fed to the Cabinet Cooler at a pressure of 100 PSIG. In addition, each cooler has a specified volume of air that it must utilize in order to produce that rated cooling capacity. If any one of those parameters change, so does the overall cooling power.

In this particular case, the customer had installed a non-EXAIR pressure regulator just upstream of the cooler. Upon looking at the specifications for this regulator, it was found that the overall volume of air it can deliver was just 10% of the overall volume needed to produce the rated 1700 Btu/hr. They didn’t need another Cabinet Cooler System, they just needed to remove that restriction! Upon learning that it needed 100 PSIG, they removed the regulator and supplied full line pressure. No more heat alarms for that shift!

CC undersized valve

Rather than purchasing and installing an unnecessary system, they were able to get back up and running just by removing the problem upstream. At EXAIR, we want to make sure that you’re getting the most out of our products. Just because you call and inquire about a new purchase doesn’t necessarily mean that you need it. We’re here to help you determine if something is afoul with the current setup and make sure you have all of the knowledge necessary to rectify it.

We’re right in the middle of summer, and boy is it hot out there. If you have panels that are overheating and creating problems for you in your processes, give us a call. With Cabinet Cooler Systems ready to ship same day from stock (with properly sized regulators) you can have it fixed by tomorrow.
